The forums are available using Tapatalk Forums app. To access the forums through Tapatalk you need to download the app from here. Then search for ESCipedia or JESCipedia (they will also come up in a search for ‘Eurovision‘) and select either JESCipedia Forums or ESCipedia Forums. There is no point in selecting both as they both connect to the same forum.
If you were connected to the JESCipedia forums in Tapatalk previously you will find that you need to reregister with the new style forum (unless you have already done so here).
