andrea, i think both your challenge ideas are good. right now i'm doing a monthly exercise challenge as well as the 2x2 challenge. in the past when i've done a long range challenge, i've self-destructed. i'm afraid to do another right now. i'm sure you'll have several people joining you and i wish you the best of success.
thanks.... i too am in on the 2x2 challenge as well as the august monthly challenge. my goals are 6 more by my 35th bday....9-18 and to be at goal by xmas.
challenge
same to you as well
