I agree with the comments about the templating and coding. Part of the problem with integration is the new vBulletin 4 changes. It is possibly the worst "upgrade" I have seen in a long time. With all the news about Internet Brands buying up forums on the cheap, you have to suspect whether they have something stuck in the code too. It's a terrible conflict of interest when a company looking to buy forums is also putting out the software.
Thanks guys for making the changes but I think that photopost should think of itself as more of a standalone product with login synchronization and template sync is just a bonus if it works.
