Maintenance and upgrade of www.tcoffee.org common server

T-Coffee is a complex and multifunctional package. In order to insure proper access to the many possibilities afforded by the package, we are actively maintaining a network of international servers that can be accessed through a unique entry point: www.tcoffee.org. This server is co-maintained across several institutions, including the CRG (Spain), VitalIT (SIB, Switzerland), the IGS laboratory (CNRS, Marseille). Altogether the servers receive about 2000 requests every day and are visited monthly by visitors coming from over 80 countries.
