Note about SP5ELA portals
Technological advances and software development are causing a constant headache. There is some contradiction between the substantive material and the forms of its presentation. Sometimes it is difficult to keep up with the constuctive changes of CMS systems. Word Press, Joomla, Drupal, E107, others. In the case of portals in the domain "rf.pl", and in detail the domain "sp5ela.rf.pl", the material may be scattered between different servers or sub-installations.
