Betty, you are right, it did start back with A because of the voting. Apparently, many people missed A and wanted to get it again. Only the site owner knows if the entire alphabet will be offered. I know that through A-H is posted on the site already and with a membership you can download through that letter currently. Isn't this a lovely alphabet?
The firebird alpha has only just started I believe so we can watch it grow.
I'm not quite sure what you are asking, so I will respond with both ways that this question could be going (at least in my mind). Will the whole alpha be available? Eventually, I am sure that every letter will be posted, and those who have paid memberships can download them all. As for whether they will all be freebies, it is likely since that is what has happened in the past, but it is dependant on voting. The letter that gets the most votes will ALWAYS be the next day's letter (even if it is out of alphabetical order or something). If you vote for the letter(s) you want, you are probably going to get them all, assuming that you check in daily to download each one. Good luck with that! =]
