"Done" implies its done with loco2, they exist no more, they are history.
I got an e-mail from them announcing this, effective November. They are being merged into Rail Europe.
Sounds like bad news. Loco2 was one of two independent companies, both started by a groups of young people as a response to how awful the rail-company websites were. They offered one-stop for multi-country tickets, which the national websites did not do.
They were commission-free; and they covered most (but not all) rail networks in Western Europe.
As Rail Europe is a North American operation, which charges commission and only lists some trains, there is a risk what was loco2 will in future suffer from the same faults.
The other "independent" was Capitaine Train, which then got Anglicised as Captain Train, and was taken over by Trainline. Trainline was previously UK-only, buying Captain Train allowed them to expand into Europe.
