[@souleaterfan320] Lets seeeeee, I first started with chatango a couple of years back. That is, only on writing RP. But Years before that I played on a WoW RP server. 
Read tons of WoW lore....forgot them all now.... Winner of the Best Way To Waste Time Award - Read lots of fictional lore with no use in real life and forget it anyway. I'd reckon more than 5 years certainly. There was the occasional mini roleplay chats here and there before that but nothing more. Especially on League of Legends roleplaying. Know extensive lore about it and never forgot it since I'm still playing it.
