I'm tired of telling people this. Things like this...
I want one!
...are just not acceptable. Remember when one topic is bumped up, the rest are bumped down. With my settings of 40 topics per page there are topics in this forum that cover about 15 days. Thus if someone posts a topic in there it'll be reasonably viewable for 2 weeks, so there really is no need to bump. If no one wants your items please just accept it; there's no need to be selfish and sabotage someone else's chance.
What is classed as bumping? Well the ones above are blatant examples but several "updates" in a row without any posts from other members is much the same. Ultimately the best way to tell is simple; ask yourself why are you posting. If it's really to add something you should be OK, but if you have any doubts, or if little or no interest has been shown in your post, then you probably shouldn't post the update. There are other ways to sell LEGO after all.
Repeat offenders (especially those who have large percentage of posts in the BSTF forum) will be banned from posting in this forum. We do keep track of warnings.
Having said all of that, what can we do to satisfy peoples urge to bump? Well aside from dancing we do accept people adding links in their signature to a sales page or to an on-line store. If you're making loads of sales that's probably more appropriate anyway. Also, an idea that I was considering was to add a topic where people could post wants and haves, and that way people could bump away without being as annoying, and it'd also be a good place for sellers/buyers to browse.
Please feel free to post your thoughts on this issue.
