I usually just find that the glass is wrongly sized for the amount of liquid it contains. :-)
Anyway, I fear I'm going to rain on your parade here. If it's just a forum you're wanting, than I'm sorry, but this isn't the place. I look for people (and/or furs) who are going to provide creative content to share with others. That basically means art, comics, stories, that sort of thing. Community sites, while great, aren't the focus here. Sorry!
Best of luck to you though, I'm sure you can find something pretty quickly that meets your needs.
