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.

  • Mortar for below grade foundation

    I'm putting in a block foundation below grade. What is the best type of Mortar to use for this application? I have two books from the library, one says to use Type S, the other says to use Type M. Does it matter?

    Re: Mortar for below grade foundation

    Here's a good summary of the various mortar types and their properties: link

    Either type M or S should work for your foundation wall, but S might be best. This is from the mason contractors website:

    "It should be remembered that stronger is not necessarily better when selecting mortar for unit masonry. For example, it is not typically necessary to use Type M mortar for high-strength masonry. Type S will provide comparable strength of masonry, and in fact the Masonry Standards Joint Committee's design standard ACI 530/ASCE 5/TMS 402 does not distinguish between the structural properties of masonry constructed using Type S mortar from that constructed using Type M mortar. Moreover, Type S and Type N generally have better workability, board life, and water retention. As a rule of thumb, the specifier should not require use of a mortar of higher compressive strength than necessary to meet structural design criteria."

    What is that strength?

    "The five typical mortar mixes designated types M,S,N,O and K are labeled so because each is an alternate letter in the term MASON WORK in descending psi strength....

    M 2,500 psi
    A
    S 1,800 psi
    O
    N 750 psi

    W
    O 350 psi
    R
    K 75 psi

      Good info there! Strength is a relative term though. Compressive, tensile, shear...
