You just need to track them down on the internet. There are other trainer sites that give you full access and chat privileges and actually have people who respond to your messages. Just means I am out of pocket something the cost of a train-fare. I'm glad I wasn't on a monthly sub or something because its basically not worth it. I only ever donated once, that was around $5. Ignores request updates and ignores mail. Mr.antifun has turned into one of those developers who has distanced himself from from the community on a backbench. Ever since then the site has been empty, unhelpful and have not been maintaining their trainer updates. I have been a member of the Antifun site for just under a year and it was not long after I joined it then merged with Wemod.
The admin there are two-faced where they fake innocence and play a victim when people confront them with issues - I have dealt with two of them so far. No customer support and no connection with their consumers. Used to like the site but it has all corporate now thanks to that Wemod trash.
