The conversion of all articles from Joomla to WordPress is done. That is; it is acceptable for me. Still some articles have to be update with some pictures, but all relevant articles are there. It is possible to download files (you have to register first). To prevent a lot of bot activities, Captcha is active for the available forms and for registration and login actions. The state of the site (information) is equal or better then with joomla. Ready for the future. Thanks to the boys of Yourhosting.
