[Haskell-cafe] claiming maintainer position of a HackageDB package

Hi, I would like to submit a new version of the following package: https://hackage.haskell.org/package/mime-string Unfortunately, I only received private consent from the current maintainer that I would become the maintainer of this package, more than one month ago. Since then I had not received any answer to my request and I cannot upload a new version to HackageDB. Is there a procedure I could summon to become the maintainer of this package on HackageDB? Thanks Guillaume PS: for the anecdote, darcsden needs this new version of mime-string.
