I got invited to Alpha Skip-Ahead. Should I?

Alpha/Alpha skip ahead is as far as i know by invite only. You should been an insider for a long time and give proper feedback to the builds.

You must be invited to become an Alpha Insider or Alpha Skip Ahead Insider, to do so You must Very active in Xbox, doing missions and report the bugs You see in the system, as much as You do this, so You Will be Very close to become an Alpha Insider. You
must be at least in Delta preview to become an Alpha Insider, but You Just need to be an Insider to be invited to become an Alpha Skip Ahead, but this one is very rare to be invited and there is a certain number of people to be invited, no more than that,
If You were not invited to be Alpha Skip Ahead certain time, so You must wait a Second chance when they Will invite New members.

It was a 50/50 chance between Alpha Skip Ahead and Alpha rings. I don't know how you would know others have not put in the time but if they are in Alpha Skip Ahead or Alpha rings they have been invited in as people whom file the best most accurate reports.
It is inevitable that some aren't as active as others.

Also you should really be posting your concerns here https://www.reddit.com/r/xboxinsiders

Hi

Unfortunately once the Alpha Skip ahead tier reached capacity and they had to stop accepting additional new members. When the invites were sent out there would have been places available in the Alpha Skip ahead group however once these
places filled up no additional members (even with invites) could join at this group.
