I think it's only fair. Most things cost a small fee when you use em to make money(ebay, paypal). It might be a complicated thing to get going but would be a good thing for the site. Could be something small like 2.5% - 5%. I've seen people donate after making money so it'd pretty much be the same thing. There's a lot of people that join only to make money and don't have any real desire to contribute to the site, only looking to make some cash. Just something I was thinking about while seeing all the different paid services going on right now. 2.5% of everything that they are making going back into the site would add up. could help and lead to better things down the road as the site grows even more.
This is actually a good idea. I keep experiencing problems with the site such as it not loading or taking ages to load. This could help towards keeping the site up as-well as other parts around the site.
