Don't you dare quit!!
Seriously, this has been my worse month for time too, even if you post later on it will still count (only if you can). I know my Feb is a bit rough, and March is looking a bit the same, but it's the whole group, and of course writing new songs that count. You know how hard osam can be, and that's part of the appeal - it makes us strive and push on. It would be so easy to sit back and just take in the other guys work here, but I think we all look forward to listening to next new song posted (maybe more than our own sometimes) gives us inspiration too.
Post what you have, and finish it when ever, or wait and post one every month, one every two months, three every day - it's all good
There will be times when we have to say I can't continue, but knowing you I hope that time is not yet!
