Erano presenti tutte le 19 Delegazioni regionali, in rappresentanza delle 20 Regioni e 10.712 Soci (il numero si riferisce agli aventi diritto al voto al 31 dicembre 2022).

Abbiate fiducia nei sogni Mauro Pregliasco, I1JQJ Uno fra i compiti più ingrati, se non il più ingrato in assoluto, che spettano al Segretario Generale è comunicare ai Soci le nuove quote stabilite dal Consiglio Direttivo. Come si suol dire, è uno sporco lavoro, ma qualcuno dovrà pur farlo. L'aumento della quota associativa, nella misura suggerita dai dati a disposizione, è sempre una decisione ostica ed imbarazzante, che procura disagio agli Amministratori. D'altra parte, bisogna sempre avere a mente che chiudere un esercizio in perdita potrebbe comportare una non approvazione del bilancio, con il conseguente blocco delle attività. [...]
