Feel free to use any method you like in order to create the character, but you are kindly requested to post the character in text here: Johnathan's Dungeons & Dragons Character Creation, in the character creation thread, as instructed there! Thank you :)
You are making great progress. There is actually a generator available and the SRD is also there. Your Johnathan's Dungeons & Dragons Character Creation has been updated to reflect this.
Welcome, Felipe. You seem to be a longstanding member of this community, and you are certainly accepted to join. Please follow the link mentioned in my previous post to read more about generating your first character.
Some helpful tips
1. Make sure you know the rules here, you will avoid having your Posts constantly edited. You were given the various links already.
2. In no where on your Character Creation Post do you state to use a Dungeons & Dragons 25 point-buy system and yet after Players have gone through the process of creating their Characters you ask them to do it over using that. Why not state so up front?
3. Rather than tell the obvious, that you cannot link, why not just show them how to do the 25 point-buy system manually, in that way they do not have to ask or go searching.
4. If everything is clearly written then Playing a game will be easy 1-2-3 steps. I've seen many prospective Players lose interest when they have to go through too many things to start.
Changing ability scores is an easy task. As for linking, I linked to a free to use, with no ads calculator to make it easier for them. I had completely forgotten about the ability scores for whatever reason.
I'm a slow learner when it comes to these things. Please bare with me here. I never claimed to be the brightest guy around here.
Johnathan, we are not asking you to be the brightest, just to follow the rules and tips we give. They have further reaching purposes than what you may see on the surface.
Welcome Greek Dungeon Master! I wish you luck in your campaign and I hope you stay for the long haul and not give out suddenly like my last Italian Dungeon Master. ;)
