Hi, I'm a relative newb to this so it may be a dumb question, when setting up the mysql db to connect to, on my test server I have a size quota associated with the db, how big can I expect one mysql db to get,based on # of posts/images, etc. This is a 4-500 user bbs right now. (we are tight on disk space at the moment so I have to be a bit cautious about what I add or install.)

What I've seen so far, is it's roughly 100-120 megs of storage space per 100k posts. Actual numbers will vary, but that's a rough estimate.

It can and will vary, your host likely has a limit ~100mb as thats wht I've seen average on this type of limiting. If it's anything below say 500mb-1gb I'd think about relocating, but that's just me
