sign up reminder

[lilly_c]

I would have this posted earlier in the week but forgot to, anyway there is still a little over a day to sign up for March's challenge here.

I also need volunteers to help out with the daily check in for the weeks of 1st to 7th, 8th to 14th, 22nd to 28th and 29th to 4th. It would be nice to see others helping out with the comm too as well as the regulars.
