Trading's fun, especially around when new main series games are released since activity tends to spike by a lot. I'd definitely recommend the Trade Corner as Rainbow said regardless of what time period, it's pretty popular overall. =p
And of course welcome, Ruby, lovely to have you! Would be fantastic if you'd end up sticking around as an active community regular, there is a lot to get involved in and our members are very friendly & welcoming.
If you need anything just ask, otherwise enjoy your time. <3
