A friend showed me GO webmail system and it is very nice, I enjoyed it. However, I noticed and he commented that some features have taken quite some time, such as the mobile interface or threaded view of emails.
We're truely considering purchasing GO for our ISP, to offer it as a service. I would like to have more concrete information on future plans. When is a new revamped version expected? Is there a roadmap of the product that we can follow with the main features and improvements that are planned?
