You need to ask yourself the following (and in this order):
1.What do you hope to accomplish?
2.Do you have a target audience in mind, and if so, what message do you wish to provide to that audience?
3.Do you wish that audience to respond in kind?
4.Are you able to share photos, or as poster "pissclams" mentioned, do you have anecdotal gems from your personal life you would like to share with the board?
5.Do you harbor racist feelings? I hope NOT!
6. _____________________(Make up a question to ask yourself!)
7.Are you a bbs'ing trailblazer? Tell yourself you can be, and figure out what trail you will blaze! I think the answer is Yes, but what do you think.
8.Do you use formatting in your posting? Not many here do. Maybe this is where you can shine!
Best of Luck!
