Hi Zheng, >Yes as you said Emule is okay. But Edonkey (which you mention) isn't. I don't recommend using eDonkey software, and I never did. It used to bundle spyware in the past, and it's not free, it shows ads, and it has closed source so only its developers know what it's really doing on your machine. >But bittorrent is getting really popular as Vincent says. I would prefer if it >was on the bittorrent, While BitTorrent is also OK for sharing tablebases, eMule is more suitable for long-term sharing of 1 TB of data, as I said earlier. BitTorrent is more fit for relatively short time 'release' of some new files. It is not particularly good for long-term sharing, or for sharing of too much volume of data. I will explain in detail. Original BitTorrent is not decentralized - every shared file must have a 'tracker'. When the 'tracker' goes down - no one can download the file anymore. The user who shared the file first creates and hosts the 'tracker'. This scheme is good for release of a new file, when 'releaser' has a web-server and when he is sure he can host the 'tracker' for long enough time. For example a number of linux distros are using this way of distribution. On the other hand, tablebase sharing is done by ordinary chess hobbyists like you and me. Many of us don't have a web-server, many of us don't keep our machines on day and night, etc.. And even if someone can take on the responsibility to host the 'trackers', who can guarantee that his 'trackers' will be online in one or two years? Chess rules are not likely to change soon, so the Nalimov endgame tablebases are here to stay for many years to come. At least 6-men tablebases that we will use in 10 years will probably be the same ones we are using now. For such long-term project eMule is more suitable. Decentralized system based on using both eD2K and KAD networks is very robust, and no one has to take any obligations or responsibility - anyone can join, download files, and keep them shared for a while. Several times on eDonkey network I could find files that I used to share and deleted about three years ago. Someone else kept them shared, and now I still can download them. This is what we hope to achieve with EGTB sharing - constant availability, in long term. One can say that recent BitTorrent is going 'trackerless', but officially it is still Beta software, while eD2K network and eMule software are stable for several years. (Although KAD network is recent addition). One detail. When I tried BitTorrent last time I found that many BitTorrent clients limit the number of files you can share. I don't know if it's still the case, but eMule does not limit number of shared files in any way, you can share hundreds of files without any issues. Also, while I agree that BitTorrent is popular, you can't claim that eDonkey network is not popular. After all, eDonkey is _the most popular_ p2p network currently, according to the number of studies. For example Slyck (http://www.slyck.com/index.php) shows up to date statistics. Best, Kirill
