Here's how Wingtips works. If you have a tip on screenshot technique, anything related to image editors, angles, add-ons, composition etc..you can submit the idea in a 2 or 3 line thread. Something like this:

You'd title your thread Wingtip, then inside, you could write something like "I feel the best image editor available for screenshots is Irfanview". Then maybe leave a link to it. Or how about something like.."I've always felt Holger Sandmanns' meshes are incredible, particulary BCmesh2..then again if you're feeling motivated, include the link.  If this idea is popular and we build a lot of simple and helpful "wingtips", the library will grow fast and become an even more helpful place to visit. What do you think?  

All the Wingtips can be found here
