Abstract
The Internet is extremely important for the publishing of information and for the interaction between the society elements. Due to this, it's essential that the web presents itself accessible to all, including those with any kind of disability. An accessible web may help the handicapped citizens interact with the society in a more active way. This paper presents a study made with a universe of 777 Portuguese biggest enterprises, using a W3C referenced tool (SortSite), and presents some statistical results according to the Portuguese Classification of the Enterprises Activities. The achieved results present a serious troubled reality that's preventing the disabled citizens from having the same access rights to the World Wide Web as the "non-disabled" citizens.

This article proposes a model for e-Learning 2.0 that can be implemented on a social network, and discuss its advantages by supporting the education and training throughout life and in designing new models for distance learning.

Abstract
Web accessibility is growing in importance as each day goes by. Alongside this growth, is also the need for access to web resources, by those with some sort of disability. The web is very important for spreading information and for the interaction between the various society elements. Given this, it is essential that the web presents itself as a totally accessible resource, so that it can help disabled citizens in their integration within society. This obligation should be greater for enterprises where the web is used as a marketing and business platform. With this paper we would like to present a study with indicators regarding the accessibility levels of Portuguese enterprises websites and, we would also like to present a brief comparison between the accessibility levels of the 1000 largest Portuguese enterprises websites and the accessibility levels of the 1000 best Portuguese SMEs websites.
