Bumping?

I am very new to doing this I posted some items in the classified I found out it's very hard to ship some items. lots of questions going back and forth I think I answer them in the wrong place I don't know what that means but that was told I am bumping. I have not sold car parts in 30 years last time I sold parts we did it in the newspaper. I am not very good with computers or navigating through this site Should I go to a different site that may be easier . Can someone recommend one
Welcome, and yes sir, bumping a for sale add with to much talking and bringing your for sale to the top of new posts is not fair to everyone els that is selling, I do agree with questions but going back and thanking a member for info brings your post back to the top (Bumping add to the top)
I understand the feeling about not knowing these computers as well, been there and still not very good with them, did you read the rules on selling ?
