I didn't notice anything about whether or how often it's allowed to bump a request.
I basically have only done it on the odd occasion when I was able to offer more points or something.
If a monthly bump or something is acceptable, maybe some of my old requests can get filled.
I'll wait for some responses.
My opinion..I Think, when an item is fresh, a week bump or something is OK. After that a 2 weeks bump and after that a 3 weeks bump and so on. Bumping many items @ ones is for me not acceptable...Is like people posting around 10 items a day.
Yeah, I was thinking once a month at max.
There are a few old items I've never seen at places like this and as my budget is minute, I don't want to buy before I try.
Offering more points is a valid reason to bump posts. But as Dimer says, after a few bumps without response you're very unlikely that it will be filled.
