Feel free to make a thread whenever you have a question. I know there is a topic under MLS Discussion

As far as why it's closed down... Not for any particular reason.
It's just easier going forward if we discuss things in order of the MLS season. Winter Transfers and Summer Transfers and by year.
If it continues to go on year after year you'll have thousands of pages of useless information that someone has to go through to find out where informative posts start that actually revolve around that transfer window.
Doing it this way you know from page 1 all the way to the last page it pertains to possibly transfer targets.
For the Pirlo thread, it was a bit all over the place and the new one will be locked soon and discussion transferred to Roster section. Same with Iraola and Angelino. Just as we've done with all signings in the past.
