  • One complaint about SX5 is that there is no good and up to date helpweb page (at least in English) for the users. They have changed now thecommands for submitting jobs etc. I have received e-mails concerningthose changes but the main body is in Japanese. It would be helpfulif there would be a web page with such info. in English (perhaps there isand I dont know)It is also not clearly stated anywhere which are the available disks and their characteristics, it seems that in some of them data is removed ifnot used for a certain time. Anyway, SX5 works much better than any of the systems I have used in Spainso I don't want to complain too much. SX5HELPE- SX5
