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.

    Re: what grade of vermiculite

    Coarse to medium. You're trying to create air space within the material to trap the heat, so powdery stuff isn't preferred.

      Yes that's true, you don't want powdery, but the fine vermiculite makes a more workable mix although it takes more water. I doubt whether ther is any measurable difference between fine med or coarse in the final product, after all a bucket of small marbles weighs the same as a bucket of large marbles. The spaces maybe bigger but the volume of the spaces is the same. Try 50% perlite 50% vermiculite it makes a good workable mix with minimal cement needed to hold it together

        I figured you are using it for enclosure filling. But if you're doing an igloo, I'd go with david's suggestion.

          Yeah,sorry, I was assuming you we're doing an igloo. If doing an enclosure go with azatty's advice. Probably less compaction with the coarse stuff.

            I am also search for the grade required for making an insulated hearth, but I can only seem to get my hands on Perlite ore down in New Zealnd.
