The following review written by one of the Software Informer contributors applies to version 5.3
Mail.Ru Agent 5.3 is an updated version of the popular instant messenger. This application is used for a number of purposes, among them are receiving e-mail notifications on the desktop, file and message exchange.
Mail.Ru Agent 5.3 has many of the same features as older versions and some new features. We can chat with our friends and colleagues and its absolutely free. All we need is a Mail.ru email address to sign in.
We can find new counterparts from any country by personal data. Mail.Ru Agent provides a possibility of voice communication and video-calls. If we want to learn more about another Agent user, we can use links in his or her profile and find out if there are any photo albums, blogs or other information added by this user.
What's new on version 5.3? They have added a lot of games. Now if we want to play, we can choose a game from a large list of 20 items.
Mail.Ru Agent 5.3 has an ICQ support. Therefore, we can use this one program instead of two. In my opinion, ICQ integrated in Mail.Ru Agent works better then when it is an independent application. The connection is stable and no advertisement appears in the program window.
