I deleted your post, as you should have posted it here, but the answer to your question is that Smogons still has a PO server... it's just a PO2 server (you need to upgrade your client). However, very few people actually use it. Most people use Pokemon Showdown, which is playable through most browsers.
Hope that answered your question. Good luck with getting back into battling!
