Just to clear up, there is the Free edition of A2 and the piad for Personal Edition. The Personal Edition has realtime monitoring etc. If you have a website and place a link to A2 you get a free copy of the Personal Edition.
If you have a personal website, and a place to link to their site, I suggest you ask them for sponsorship. A free A2, assumably with all features, is tempting, but unnecessary when other free products will do the same job (as ACOLYTE has just said). It pays to advertise, so make'em pay for the link.
