Yeah it is hard to try and think of something, what im going to do( hopefully near future) is start a forum up but a diffrent kind.
Like maybe for you, think of something diffrent(like what im doing), since there so many diffrent variety(sorry bit of lack of wording) of forums already out there...Do something complely diffrent maybe.
Something alone the lines of what your into and what you make add your own personal touch to.
If you know what i mean kinda thing.
