To summarise the outcome of discussion earlier in this topic (around post # 300):
There are supposed to be two tiers in each seed-run. One for Members and one for Regulars (which have the priority over Members).Once you reach status of Regular, you should have the privilege to participate in seed runs in Regulars tier forever.
I was suggesting to identify privileged members by looking at their Regular badge.
The problem is now that system is no longer functioning the same way. Promoting a demoting users is automatic and it does assign or remove Regular badge with the trust level.
So we will have to find out some new way to identify privileged members. For now I’d recommend to trust the user that he will insert himself into proper tier/category for each seed run and only verify it at the time of addition to the according list. (Owner of the post and also each member tracking the topic will get notification about OP post edit so they can briefly check the new participant.)
