Photo Galleries are back! Instructions below.

Dear forum users,
Thank you for your patience with the Photo galleries. We've got your galleries online!
We have finished writing a custom script to migrate the PhotoPlog to vBulletin5’s albums.

Unfortunately V-Bulletin killed the "Photoplogs" in their software upgrade which was unforeseen and we're the first development group to have written a script for getting the galleries back... that said, it took some time to reverse engineer the code and get the albums to move over seamlessly!

Forum users will be able to access their “PhotoPlog” images through their user profile page by clicking on the “Media” tab.
They will also be able to browse other albums by going to the albums page. (On the forum site, there is a link in the black bar beside “Forums” to the albums.)

In order for users to create an album please follow the steps below.
1) Go to user profile page and click “Media”
2) Click Add Photos
3) Enter Photo Gallery Title in the first field
4) Click Upload or Select from Photo Album to add photos
5) Click Post
6) Once posted, the album will be created as a “Topic” on the albums page for the public to see. The topic title will be the “Photo Gallery Title” they created before uploading their photos.

To create this migration path we used vBulletin5’s default album structure. Unfortunately, it won’t work like the “PhotoPlog” but is an album/gallery component on the forum now.

  • vermiculite/portland and weather

    I will be ready to add insulation to my slab in a few days for my WFO here in southwest VA and have a question re. vermiculite/Portland.

    Is this mixture weather resistant? I plan to extend the insulation past the edges of the dome but I am concerned about exposure in that area to the elements. Will it wick moisture under the dome and lose insulating value? Should it be waterproofed?

    Hey Jnpe,

    I can't say I remember any conversation about this question in the past, but here are my two cents on the subject...

    The vermiculite / Portland cement mixture is a very porous product. It will absorb water.

    It would certainly hold water andwhen it gets wet it will wick the water through the full structure. And if you live where it will freeze, the frozen water will break up the structure created by the Portland cement.

    I think if you want your structure to last, you will cover the exposed vermicultie / Portland insulation with tile, or stone or some product that will protect this insulation from the weather and keep it dry.

      Those builders who take their vermiculite concrete out to the edge of the support slab usually cover it with whatever surface treatment they use for the stand/structure be it stucco, tile, stone or brick face, etc.

      It's not recommended to leave your insulation open to the weather.

        Thanks for the replies!

        Most good thermal insulators by design have a high degree of porosity and just wanted to make sure I wasn’t missing something re. verm./port. Encapsulating the exposed edges with stucco sounds like a reasonable approach and planning to proceed that way.

        Found one bag of #8 vermiculite locally and have ordered the remainder.

        Thanks Again

          Definitely don't leave the vermiculite mixture exposed to the weather! See my post from last year about failed attempt to use it as a roofing material. It will continue to sorb moisture if not weatherproofed... then it will freeze and chip off in small chunks.
