Dear All, we have experienced a slight delay in posting to the bb. This was due to corruption, or excessive size, of the digest file. The solution was for the jiscmail staff to delete or current digest file. This may have the effect that no digests will be posted. Thanks to Donna for fixing this as soon as I telephoned in (she will be getting sick and tired of us/me soon). For those of you who did not get a digest, the recent archive is available at the from the jiscmail site (www.jiscmail.ac.uk/lists/ ccp4bb.html). The jiscmail staff are currently trying to upload the archive from Daresbury, which will back date things to 1996 (many years of elegant postings from EJD and others) Charles Ballard CCP4
