I am all for BSing around...I have way more wise ass/worthless posts than I do "real" Ones or serious ones...that's what this place is for....It's fun. that and when we do need help, we help each other..or at least they help me. But what you were doing makes it seem like you aren't just having fun.It makes it look like you are snubbing your nose at the members that told you about posting stuff for sale...it makes it appear that you have the attitude "I'll post it if I want to rules or no rules". Take this thread for example...you started it out ok, so I clicked on it and it's like a normal thread but in the middle of the post started advertising your stuff again. All you need to do is put a link to your ad in your signature.
Now stick around and enjoy the place .There are lots of smart people here that have helped me a bunch.
