As a domainer, even though we have our differences, my advice to you would be to drop it when it's up for renewal (both of them).
It's not worth $50, and I could go over a myriad of reasons why, the first being .org, and secondly, the uptick in "admin forums" for competition. An end user would be better off buying admin-forum.com (available) for $10 and saving $40 for an add on or towards a license or something more useful.
You renewing them hoping for an end user in this saturated market (where every forum wants to be a webmaster/admin forum for now for whatever reason) just as dumb.
Put it on aftermarket sales starting at $100 and ending at $10 to see if it even gets anything (remotely close to $50).
I could've given you this great domain name investment advice (to not buy it in the first place even) had you not been unethical and provided CloudFlare with my home IP address (in violation of your privacy policy) to blocked me from your forum. But, whatever.
Hold it. Renew it. Don't care. It's not my money.
Cut your losses and ditch it would be my advice. Peace.
