Any possiblity of doing that? I’d shell out the $75 not to have to worry about it for a decade.
Of course, soon would come May 11, 2018 & I’d be all- “I lost my Charter Member status?!?!”
Considering how the plan is to soon return to free posting, and paying only to not see ads, are you sure you want to make that sort of investment?
Is the “Charter Member” title still included? This goofball will actually pay to keep the title at $7+/yr. It’s the SDMB version of Simony. 
We dunno. Suggestion is to look at what Ed said above and hang on until we have more information, that’s really all we have to share with you now.
