I just wanted to bring people's attention to https://github.com/JuliaOpt/Optim.jl/issues/358 . Now, let me say upfront: we're not doing a popular vote, I just wanted to let people have a chance to comment.
Basically, JuliaOpt is getting streamlined such that it is only for MathProgBase and related packages (JuMP+extensions and backends). We're looking for a new name, and currently JuliaNLSolvers seems to be quite popular amongst the usual contributors. In reality, it's not super important. It's just the place for the packages to live on Github. Packages keep their names, and so on.
This new org will have a pretty specific package setup: A base package, a line searches package, the Optim package, an NLsolve-ish package (probably NLsolve exactly, but licensing issues just needs to be sorted out), and various auxiliary packages (tests etc). The idea is that the equations solver and the optimization package will have very similar code base and API (much like now, but the link will be strengthened even more).
