Topic: email address of account (Read 213 times)

2. We currently have 2,750,143 members. More stats: https://bitcointalk.org/index.php?action=stats

1) can we change the email address associated with our account or its not possible after you sign up?

As an extra protection against any possible social engineering attacks, whenever^* the administration changes an account's email address from its current value, the following process occurs:
 - The change is queued.
 - It is listed in seclog.php.
 - The old email receives a warning.
 - After 7 days, the change goes through and another seclog.php entry is added.

The account stays locked throughout all of this.

Hopefully it will be essentially unheard of, but if an account is going to be incorrectly transferred, everyone who knows about the incorrect change should noisily post all of the evidence they have so that we can at least put the change on hold and re-review the evidence.

^{* Admins can act outside of procedure and bypass the queue if necessary, but hardly ever will.}

2) is there any rough guess of how many users are there on bitcointalk.org

Derived from the information that @malevolent pointed to earlier on, @Coin-1 keeps a nice thread where the numbers are charted in an easier to read manner: [Chart] Bitcointalk statistics on impression counts for ads. 

The data was updated at the end of December 2019, and there are two interesting charts to view:

- "Unique IPs from logged-out visitors for one round (10 days)", where the most recent reading is on 94.086 IPs in that timeframe.

- "Unique logged-in users for one round (10 days)", where the most recent reading is on 13.714 users in that timeframe.

This second reading is likely the most accurate one for a short timeframe window on 10 days. There are obviously non-logged in readers that do not show on the second toll count, but are included in the first of the above provided.
Note that the timeframe here is 10 days, whilst before we were talking about larger timeframes on other readings (3 months on BPIP).


That would probably be a better reading. I could do that in relation to merited profiles, but not the rest, since I do not keep data on unmerited profiles. I did do something of the sort though a year ago (see Analysis – net posts created/destroyed in a month per rank). I thought it was pretty interesting, and from the data there (end of 2018 though) I derived that 53.858 accounts has posted in a timeframe of 1 month.

So here on this thread there are multiple possible readings, and two things come to mind:
- "Active users" will vary depending on the definition we give it (logged-in, posted at least once, etc.).
- The results will also vary depending on the timeframe (10 days, 30 days, 3 months, etc.).
