As some people has asked for, I've started with Allegro.pas tutorials in the Lazarus/Free Pascal wiki.
Some body asked me for Spanish tutorials, and also it's more easy for me to do it in Spanish, so I'll write them initially in that language. I plan to translate them to English ASAP, but if some body can do it for me it would help a lot.
Any comment and suggestion are welcomed.
