You are of course free to create a website of your own if you want to, but you don't have to do that.
If you want information, I find that Freeminds and Jwfacts are very good. I like JWFacts very much. It has a serene and polite tone and you see that the web site owner who, by the way, you can find here, is not a fanatic thirsty for blood. Not because we're talking here, but JWN (this site) is also very good, in a different way.
But, if you were or are a witness, I suppose that you know everything you need to know by now. You don't have to make sense of what you read, unlike me. You're there for the interaction and for comparing notes.
You can find a wealth of information in Spanish on Freeminds. The people at EXTJ.com can help you as well. They have a good website and some very good posters, though their community is much smaller for the obvious reason that the Spanish speaking world tends to have less access to internet and less of a habit to find information there. Also, the Spanish speaking community has been burned for a much shorter time. I don't think there are many Spanish-speaking active witnesses who have been in the religion for, say, three generations.
4Jehova.org has information in Spanish as well. However, they tend to have a more religious approach to things. I am not religious and I prefer a different approach. Now, you (and others) have a right to believe that there's a God out there and my kind of information will not be what you would like.
Those websites you mentioned are for active Jehovah's witnesses only.
