Hiya.  Just a quick post to mention that I've been using the Coinlenders site to earn interest on small amounts of BTC for a couple of months now and I've been really happy with the service so far.  I've been receiving interest on my deposit daily, and also just had a 30 day CD mature.  You can see the CD accruing interest by clicking refresh repeatedly, which is always a nice way to spend a slow work day watching my balance go up.

After seeing the site on these forums, and reading up on Tradefortress, he seems like a decent guy and I'm happy to trust him to look after my money. 

Realize I'm a newbie and therefore anything I post is completely suspect and officially void until my post count increases, but until then - that was my honest review of Coinlenders.  I'm not associated with them in any way other than as a customer.  Good service, easy to use.  If you have a few bitcoins lying around doing nothing and are happy to trust someone else to look after them in return for interest, then I'd recommend it.
