Accept Team Match Challenge?

Dear Amateur Astronomers,

I received a team match challenge from The Power of Chess.  For those of you who don't know, they have 3,000+ members, a lot of whom are very highly rated.  So, if we accept their challenge, the chances are pretty good that we will be strongly outrated.  What do you all say?

Here is the info regarding the proposed match:
