I was wondering if anyone would start suggesting moving to git or
something else ;)

Michiel - are you expecting any complications from CVS to SVN regarding
the build process?

Another thought; will existing developer accounts "just work" on the SVN
system?  Also do you (Chris) have CVS access, and if not do you need or
want it?

Sadly that didn't play with gnash 0.8, and I don't have Adobe's Flash
plugin working on my 64bit Ubuntu.  I'll have to check that out on
Windows later in the week :)

If you are able to field any queries on the mailing list, that would
probably be fine.

If you could look after that aspect of the wiki, that would be great.

The fact the CVS and SVN are relatively similar is probably one reason
why no-one has raised any real objections to the move.

In terms of timing, how long do you/the OBF guys expect the transfer to
take?  And would they prefer to do this over a weekend or mid week?

Barring any problems with Biopython 1.44 which would force us to do
another release in the very short term, I guess in the next fortnight is
reasonable (especially if we only expect a couple of days downtime).

Of course, I personally want to start working on the Seq objects and
alignments - and Tiago wants to get back to his Population Genetics module.

P.S. Would you or any of the people doing the transition be able to sort
out bug 2363?
