So i hope i'm allowed to post this question, if i'm not, i apologise.

In a recent invite i got it says it's an invite for a "Stress Test" For this friday to next monday, and that i would be accepted in the " NEXT " beta key give away if i participate.

Does this mean i can only beta test from friday to monday and then after that, i can no longer test until the next wave of betas? ( which i would assume is probably not going to happen as the release is only about 2months away )

Or am i going to be accepted with this " Beta Give Away " ?

Thanks in advance.

It means you get to beta from Friday to Monday. During the next beta weekend, which will probably be 2nd weekend in March if they keep to the monthly schedule, you will be invited to participate again.
