M90000049 has already been tested once with LL test: https://mersenne.org/M90000049
so you need a LOT of luck hoping that this LL test has an error and the exponent turns out to be prime during double checking. You can see here: https://www.mersenne.org/report_milestones/ that all exponents below 101,085,163 has been tested at least once.

Edit: Who doesn't want a flight of Mersenne primes? I have added two additional guesses. Last fiddled with by Primeinator on 20210225 at 22:32

Based on post #133, a lot of predicted dates have been passed. I believe that entitles quite a few new guesses ...

I'm waiting for Ben Delo to march over M103,305,173, then I'll have more guesses. Last fiddled with by tuckerkao on 20210303 at 03:29

Anything locates right on the border is always most debatable, example: the 18,000+ migrant kids. Last fiddled with by tuckerkao on 20210328 at 22:00

That's not what the rules say  they don't say anything about what numbers Ben Delo has been assigned. You can make a new guess after your guess and all exponents below it have been tested for primality and you wait another 60 days.
