Default Expiry date?

Is there a date/time in which the number to be tested at the latest must be tested by the computer? Does my Mersenne number have a best-before date? I know that I must "say hello" all 60 days with the server. But, in addition, is not known to me whether there is a deadline, maybe one year?

As long as you check in before it expires it will renew
your Mersenne number reservation with a new 60 days
(really 60 with 60 overdue days).
Some (very few) have been going for years.

Exclamation Too many expiry dates

The 60 day expiry date is too less. It also makes the expected completed date a useless piece of data.

I just got caught in a very bad situation. My exponent was supposed to finish in late June - starting from November 2004. I use a dial-up connection and I am offline most of the time.

In February, I decided to Quit GIMPS. But I chose to complete the exponent that I was assigned. At that time, the expected completion date was the last week of June. In addition to Quiting GIMPS, I unticked "Use Primenet", knowing that I have until late June to refresh my completion date.

I just completed the exponent few hours back, only to find that it was allocated to another person just 5 days back. I learnt about the 60 days refresh only today.

Since 60 days is an important variable, I suggest that it be put in the Status window of the program. I never thought this 60 day thing was that important. Since my expected completion date was well within limits, I thought I was safe.

Developers: Please change the network to take the expected date of completion into account and not just an arbitary value of 60 days.

If a person does not submit any update about the exponent after the expected completion date has passed, it may indicate abandonement of the exponent. But within this period, he/she may have been working, but merely offline.

I do not want to lose credit for my work and neither do I want someone else to work on the same exponent only to find that it is not prime.

Please find my reply posted here The 60 day limit is evry prominently posted everywhere. A quick glance at the readme.txt would have been sufficient.
