 Open source projects require a means for developers to communicate. These may include mailing lists, issue trackers, discord, etc. This notebooks showcases how to download data from mailing list archives. Two often used archive types are [mod_mbox](https://httpd.apache.org/mod_mbox/) and [pipermail](https://en.wikipedia.org/wiki/GNU_Mailman#cite_note-9), which Kaiaulu offer functions to download data from. The former is commonly used by the Apache Software Foundation projects. The latter, is more commonly use in GNU related projects, but this can vary. 
 
+Each mailing list maintains archives of past messages, often organized by month and year. These archives can be accessed and downloaded for analysis. However, it is important to note that mailing list archives may be split into multiple formats or locations, and not all archives contain the same information. Different archives can differ in completeness, date ranges, and the data they contain. Some archives might lack important fields like "In-Reply-To," which is important for reconstructing message threads. It is, therefore, important the archive being used is carefully selected, since this effects the quality and completeness of analysis.

 # Project Configuration File 
 
 Mailing List archives are hosted by their respective open source projects. Therefore, in order to use Kaiaulu downloaders to obtain mail data, you will need to access the respective open source project, and find out the URL tied to the archive you are interested in. Generally, that is the developer mailing list, if your interest is to understand communication patterns among developers. Alternatively, if the focus of the research is Q&A from the user base, then a user mailing list may make more sense.

+
+Mailing lists are dynamic, with new emails being added regularly. If you're conducting ongoing analysis or need the most recent data, it's important to refresh your downloaded archives. Manually redownloading all archives can be time-consuming and inefficient. The refresher functions automate this process by updating only the necessary parts of your archives, saving time and ensuring data completeness.

+### Mod Mbox Refresher
 
 To refresh these archives to ensure that you have the latest messages, you can use the refresh_mod_mbox function. This function works similarly to the Pipermail refresher.
 
 How refresh_mod_mbox Works
 1. Checks if the folder is empty and, if so, downloads the archives starting from start_year_month to the current month by calling download_mod_mbox().
 2. If the folder contains files, it identifies the most recent one using the YYYYMM found in the filename. This file is deleted, and then redownloaded along with all future months.
