Important:

 

Am reactualizat lista completa de link-uri de la index-ul de mai sus, si am mai adaugat 2, acum toate sunt functionale si toate trimit catre topicuri importante, parcurgeti asadar lista de mai sus inainte de a deschide topic nou si dupa ce gasiti topicul de interes, parcurgeti informatiile deja postate, apoi daca nu gasiti ce va intereseaza postati in topicul respectiv problema voastra.

 

Bafta.
