ReFlattr
Flattr is a wonderful thing, but every month your Flattr's reset. Meaning, if you Flattr something once, it's flattred for that one month, and then never again, unless you remember to go back and Flattr it. You can see what you flattred in your own account, or even make this public to others, but still, you have to remember to go back and Flattr.
This is where ReFlattr comes into play. You can signup, using any name you want, you don't even need an emailaddress to use ReFlattr (although it might be a good idea to supply one so you can reset your password in case you forget or lose it). After that you can link your Flattr account with your ReFlattr account, without giving out your password! From there on out, you can see on Reflattr what you have flattred this month and select those things that you wish to be flattred again. You have the choice between no ReFlattr (same as now), ReFlattr forever (or until you run out of means/change it in ReFlattr) and ReFlattr X times, where you can enter a number of how many times it sould be ReFlattred. At the beginning of each month, ReFlattr will Flattr in your name the things you chosen.
ReFlattr is currently in an alpha stage, but will open a public beta as soon as possible. Stay tuned!
